Django ModelForm with ManyToManyField showing all possible objects
I need your help with this. I tried to find the solution for a couple of days, but no luck so far. Here is the set up: There can be several projects, tasks and people can be assigned to projects, a person can be assigned to several tasks, and the same task can be assigned to different people. No problems so far... When I try to show a form for a specific task (which is assigned to 1 project), it shows all people from all projects, but I need to see people only from the project associated with the selected task. Thank you very much in advance! class Project(models.Model): project_name = models.CharField(max_length=50) def __str__(self): return self.project_name class Person(models.Model): person_name = models.CharField('Person Name',max_length=50) project = models.ForeignKey(Project, on_delete=models.CASCADE) def __str__(self): return self.person_name class Task(models.Model): task_name = models.CharField('Task Name',max_length=50) project = models.ForeignKey(Project, on_delete=models.CASCADE) people = models.ManyToManyField(Person) def __str__(self): return self.task_name class TaskForm(forms.ModelForm): class Meta: model = Task fields = ('task_name','people',) -
Using filters on Django 2.0
Please help to find the reason of error. Have two objects which ones returning from my view : def managment_users_form(request): users = User.objects.all() usersinfo = usersinfo_model.objects.all() count_objects = users.count() if request.user.is_authenticated: username = request.user.username context = { 'users': users, 'usersinfo': usersinfo, 'count_objects': count_objects, } return render(request, 'users.html', context) else: return redirect('login_form') And on my template I want to make for cycle from first one and filter by id in cycle another one. First is working well, but second one I'm getting error when try to use filter. Teamplate {% for user in users %} <div class=""> <h4 class="m-b-5">{{ user.first_name }} {{ user.last_name }}</h4> <p class="text-muted">{{ useremp|user_info_filter:user.id }} <span></p> </div> {% endfor %} filter from django import template register = template.Library() @register.filter(name='user_info_filter') def user_info_filter(useremp, id): return useremp.filter(user_id=id) Please help to understand the mistake. Error is : "Invalid filter: 'user_info_filter'" -
How to return 400 error for unique_together constraint violation?
I am using Django-Rest-Framework and have a model with the following constraint: unique_together = ("title", "owner") When that error is encountered the server sends a 500 response to the client, but I want to return a 400 error and detail of the constraint, so I can show it to the user. Here is the serializer code: def create(self, validated_data): title = validated_data.pop('title') try: poll = Poll.objects.create(title=title, slug=slugify(title), **validated_data) p = Poll.objects.get(id=poll.id) [p.tags.add(tag) for tag in validated_data['tags']] return poll Is it possible to raise the error there? -
django-admin.py not running
I'll add another django-admin.py question, as none of the other questions seem to cover my issue: I've installed django via pip: $ pip install django My pip and Python versions are: $ pip -V pip 9.0.1 from /usr/lib/python2.7/dist-packages (python 2.7) Specifically, python is version 2.7.14. At this point I expected to run $ django-admin startproject myTestProject which would then create my project folders in the current directory. However, this returns Cannot find installed version of python-django or python3-django This confuses me, since when I ran $ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin Further, I checked where the file django-admin.py is located: $ find -iname "django-admin.py" ./.local/bin/django-admin.py ./.local/lib/python2.7/site-packages/django/bin/django-admin.py So it seems like django-admin.py is in my PATH. Why then can I not run it? (extra info: I do have python 3.6.3 installed, too. But I don't think this version has anything to do with pip or django.) -
Good practice for doing a Django media backup
Is there any good practice for doing a Django media backup? I know there are tools like https://github.com/django-dbbackup/django-dbbackup but I can't make it work with management.call_command("mediabackup") when using options, I want to specify the generated tar file name, so I can upload it to a remote storage. I actually opened an issue about that https://github.com/django-dbbackup/django-dbbackup/issues/278 So, I'm looking for a way of doing my own backup. It looks like making a compressed version of the media folder is just what's necessary, but I'm not sure (mediarestore seems to to some stuff on the background) so I'm looking for good practices or example. -
Strange behavior of super() in Django Model
I use django 1.8.8, django-rest-framework 3.3.0 and python 2.7.12 on ubuntu gnome 16.04. I have a django model MyModel. In that model I override the save method in the following way: def save(*args, **kwargs): ... super(MyModel, self).save(*args, **kwargs) ... The problem that I found is that sometimes super is called as a usual function and after its call the next line is executed. But sometimes it is call itself recursively and we go to the first line of the function. When it is called from unit tests as self.client.post(...) the behavior is recursive. When it is called from unit tests as MyModel.save() the behavoiur is normal. Also I found that when it is called from client there are empty args and kwargs. But when it is called as MyModel.save() there are the following kwargs: kwargs = {'using': 'default', 'force_insert': True} I modified my code: def save(*args, **kwargs): ... kwargs.update({'using': 'default', 'force_insert': True}) super(MyModel, self).save(*args, **kwargs) ... But this don't change the recursive behavior. It would be great if someone tell me how to fix that. -
Correct setup of django redis celery and celery beats
I have being trying to setup django + celery + redis + celery_beats but it is giving me trouble. The documentation is quite straightforward, but when I run the scripts, nothing logs to any terminal, as if no tasks where being run. I have only one task, all that it does is printing and logging something. This is my folder structure: - aenima - criptoball - celery_aenima - __init__.py - celery_setup.py - tasks.py celery_setup.py looks like this: from __future__ import absolute_import, unicode_literals import os from celery import Celery # set the default Django settings module for the 'celery' program. os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'aenima.settings') app = Celery('criptoball.celery_aenima') app.conf.broker_url = 'redis://localhost:6379/0' # Using a string here means the worker doesn't have to serialize # the configuration object to child processes. # - namespace='CELERY' means all celery-related configuration keys # should have a `CELERY_` prefix. app.config_from_object('django.conf:settings', namespace='CELERY') # Load task modules from all registered Django app configs. app.autodiscover_tasks() app.conf.timezone = 'UTC' @app.task(bind=True) def debug_task(self): print('Request: {0!r}'.format(self.request)) and tasks.py looks like this: from __future__ import absolute_import, unicode_literals from datetime import datetime, timedelta from criptoball.celery_aenima.celery_setup import app import logging from django_celery_beat.models import PeriodicTask, IntervalSchedule cada_10_seg = IntervalSchedule.objects.create(every=10, period=IntervalSchedule.SECONDS) actualizar_candles = PeriodicTask.objects.create(interval=cada_10_seg, name='actualizar_candles', task='celery_aenima.tasks.actualizar_candles', expires=datetime.utcnow()+timedelta(seconds=30)) @app.task def actualize_candles(x, … -
Django Rest Framework - self.request.user in model method
I have a model: User is the django User model from django.contrib.auth.models # drink/models.py class Drink(models.Model): name = models.CharField(max_length=32) bartender = models.ForeignKey('bartender.Bartender') # bartender/models.py class Bartender(models.Model): name = models.CharField(max_length=64) owner = models.ForeignKey(User) # property/models.py class Rating(models.Model): bartender = models.ForeignKey('bartender.Bartender') owner = models.ForeignKey(User) I use django rest framework and would like a serializer Field as such: # bartender/serializers.py class BartenderSerializer(serializers.ModelSerializer): rating = serializers.IntegerField(source='get_rating', read_only=True) class Meta: model = Bartender fields = [] My Viewset is class BartenderViewset(viewsets.ModelViewSet): queryset = Bartender.objects.all() serializer_class = BartenderSerializer how do I add a model method to my Bartender model, such that it returns the Rating object for whatever User is making the call. I tried this modification to my Bartender class: # bartender/models.py class Bartender(models.Model): name = models.CharField(max_length=64) owner = models.ForeignKey(User) def get_rating(self): return Rating.objects.get(bartender=self.id, owner=self.request.user) However self has no request.

python convert timezone issue
I have Jalaali date and time as Iran timezone,what I want to do is convert them to Gregorian date and UTC time respectively and separately and then create a Django datetime object to save it in my model ,everything works fine but when I try to save it , it saves previous value for them (before converting with astimezone), but if remove the tzinfo from datetime object the save problem goes away this is my code: import datetime import pytz gregorian_dict = {'gy':2018,'gm':2,'gd':3} time_list = [9,0,0] gregorian_date_iran_time = pytz.timezone('Iran').localize(datetime.datetime(gregorian_dict['gy'], gregorian_dict['gm'], gregorian_dict['gd'],time_list[0],time_list[1],time_list[2])) gregorian_date_utc_time = gregorian_date_iran_time.astimezone(pytz.utc) so far everything is Okey and the output is desired, but when i try to save it the value for gregorian_date_iran_time is save instead eventhough the prints is desired values suggestion = Suggest() suggestion.request = online_request suggestion.teacher = teacher suggestion.session_length = length print(gregorian_date_utc_time) # 2018-02-03 05:30:00+00:00 suggestion.date = gregorian_date_utc_time print(suggestion.date) # 2018-02-03 05:30:00+00:00 suggestion.save() but when i do this,i get correct result after save gregorian_date_utc_time = gregorian_date_utc_time.replace(tzinfo=None) I dont know if I am making a dumy mistake or forget something what is the solution for this? -

Django: How to filter related objects based on different criteria?
I'm working on a 'workflow management website' where different workflows with different steps can be tracked. A workflow is defined by a number of steps with a given order. A 'Job' realizes the workflow and 'Tasks' realize the steps. class Workflow(models.Model): name = models.CharField(_('Name'),max_length = 100, unique = True) class Step(models.Model): workflow = models.ForeignKey( Workflow, on_delete=models.CASCADE, ) name = models.CharField(_('Name'), max_length = 100) order = models.SmallIntegerField(_('Reihenfolge')) class Job(models.Model): workflow = models.ForeignKey( Workflow, on_delete=models.CASCADE, ) def current_task(self): # first task without finished date my_tasks = self.task_set\ .filter(finished__isnull=True)\ .order_by('step__order') if my_tasks.exists(): return my_tasks.first() return False class Task(models.Model): job = models.ForeignKey( Job, on_delete=models.CASCADE, ) step = models.ForeignKey( 'Step', on_delete=models.CASCADE, ) assigned_to = models.ForeignKey( User, on_delete=models.CASCADE, ) The current task of a workflow is the 'first' task without a 'finished' date (ordering is given by task.step.order). If there is no such task, the job is finished. My question is how to filter current tasks for a number of jobs. For example I want to filter Jobs where the current task is assigned_to some user. So far I used a for-loop and checked job.current_task().assigned_to for each job, but this obviously is a pretty slow/dumb way of doing that. Is there a more efficient way? I … -
Redirecting to a separate Django view after Ajax request is successful
Django/Python server-side dev here. And also a JS newbie (8 days old). This question is about Ajax-initiated page reloads. Here's a JS snippet where I'm processing the JSONResponse from a Django view I POSTed some data to. Depending on success or failure, you'll see that I'm calling a redirect to another Django view: var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function() { if (this.readyState == 4 && this.status == 200) { var resp = JSON.parse(this.responseText); if (!resp.success) { console.log("Failed!"); } else { console.log("Success! Redirect to: ", resp.success_url); window.location.href = resp.success_url; window.location.reload(); } } }; xhr.open('POST', e.target.action); xhr.setRequestHeader("X-CSRFToken", get_cookie('csrftoken')); xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest"); xhr.send(form_data); Specifically, the following lines do the trick: window.location.href = resp.success_url; window.location.reload(); My problem is that when this gets executed in Firefox, I am made to see the following dialog box: It seems the POST parameters are being sent again ?! How do I just do a plain old GET type redirect to resp.success_url instead? Please advise and let me know if you need more information. Note: let's stick to pure JS for the scope of this question - I'm learning vanilla JS these days and don't want to get into JQuery prematurely. -
